Abstract
Athermal micromachining with picosecond pulses was demonstrated to be very efficient for many materials. Processing with ~10 ps pulses has the advantage of using Nd-doped based technology which is diode pumped and very efficient. A lot of commercial products are based on this technology. The weakest link of these standard products is the expensive high repetition rate Pockels cell in a regenerative amplifier, which allows repetition rates up to 100 kHz. More versatility in the repetition rate is needed. We report on the development of an efficient and simple picosecond diode-pumped solid-state laser source with versatile repetition rate (typically lHz-lMHz) for material processing applications.
